Question #70d19

Answer 1

`4/5`

Explanation:

So the bag contains:

`4+3+8=15` fruits

The probability to choose a grapefruit at random is:

`3/15=1/5`

Therefore, the probability that a grapefruit is not chosen is:

`1-(1/5)=4/5`

Answer 2

`P(E)=12/15=4/5=0.8`

In other words there is an 80% chance that a grapefruit is not chosen.

Explanation:

Total number of entities in the bag=4+3+8=15.
No. of fruits which are not grapefruits=15-3=12.
Therefore the probability of the event E that a grapefruit is not chosen is,
`P(E)=12/15=4/5=0.8`

In other words there is an 80% chance that a grapefruit is not chosen.
